Answer: Option C

Explanation:

***The question is erroneous.

Let the number of each type stamps is S.

Now, 10 TK = 10 x 100 paisa = 1000 paisa

So, 20S + 30S = 1000

or, 50S = 1000

or, S = 100/50 = 20

So, the number of total stamps = 20 + 20 = 40

Answer: Option B

Explanation:

Let, Original selling price be x

After increaseing 12% then the price x + 12 of x = 1.12x

Now, vat to be paid 10% of 1.12x = 0.112x

Need profit = 0.12x - 0.112x = 0.008x

According to question,

0.008x = 64

x = 8000 Tk.

1433 . Bill and Ben can clean the garage. together in 6 hours. If it takes Bill 10 hours working alone, how long will it take Ben working alone?

A. 11 hours
B. 4 hours
C. 16 hours
D. 15 hours

View Answer	Favorite Question

Answer: Option D

Explanation:

Let's use the concept of work rates to solve this problem.

Let B represent Bill's work rate (how much of the garage he can clean in one hour), and let C represent Ben's work rate.

According to the problem, Bill and Ben can clean the garage together in 6 hours, so their combined work rate is 1/6 of the garage per hour.

So, we can write the equation: B + C = 1/6

Now, it's given that Bill takes 10 hours to clean the garage alone, so his work rate is 1/10 of the garage per hour: B = 1/10

We want to find out how long it takes Ben to work alone, which means we need to find C.

Now, we can substitute B into the first equation: (1/10) + C = 1/6

To isolate C, we'll subtract 1/10 from both sides of the equation: C = 1/6 - 1/10

To subtract these fractions, we need a common denominator, which is 30: C = (5/30) - (3/30)

C = 2/30

Now, simplify the fraction: C = 1/15

So, Ben's work rate is 1/15 of the garage per hour, which means it would take him 15 hours to clean the garage alone. Therefore, the answer is 15 hours.

1437 . Brighto soap powder is packed in cubeshaped cartons. A carton measures 10 cm on each side. The company has decided to increase the length of each edge of the carton by 10%. How much has the volume increased? (cc = cubic centimeters)

A. 10 cc
B. 21 cc
C. 100 cc
D. 331 cc

View Answer	Favorite Question

Answer: Option D

Explanation:

Initial volume = 10³ cc = 1000 cc

New side length = 10 + 10% of 10 = 10 + 1 = 11

New volume = 11³ cc = 1331 cc

Increase in volume = 1331 - 1000 = 331 cc
